FIELD: physics.
SUBSTANCE: double guidance of beam is used in hybrid optical-type antenna (HOA): electronic and mechanical. Electronic scanning in the HOA is carried out by switching method with amplitude and phase change. Periodic travel of field of electronic scanning is reached by means of mechanical scanning.
EFFECT: increase of scanning speed at reduction of sizes of active phased antenna array.
